ASH-SIFTER.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed October 16, 1906. Serial No. 339,180,

T on whom it 'Il'l/(Ly con/corn:

Be it known that I, PATRICK M. STANTON,

a citizen of the United States, residing at Troy, county of Rensselaer,and State of New York, have invented certain new and useful Improvementsin Ash-Sifters, of which the following is a specification.

; shaft therethrough.

The invention relates to such improvements, and consists of the novelconstruction rection exteriorly of the inclosure.

and combination of parts hereinafter described and subsequently claimed.

ing drawings, and the reference characters marked thereon, which form apart of this specification.

Similar characters refer to similar parts in the drawings.

The single figure of the drawings is a central vertical longitudinalsection of my improved rotary ash-Sifter, with the central shaft andworm shown in side elevation.

The principal object of the invention is to control the escape of thecinders from the sifter and to provide for accumulating the cinderswithin the sifting-cylinder until it is desired to remove theaccumulation of cinders therefrom. This I am able to accomplish bylocating in the lower end of an inclined sifting-cylinder a worm adaptedwhen the cylinder is rotated in one direction to feed out i from thelower end thereof the contents of such cylinder, but when the cylinderis rotated in the opposite direction to act as a stop to prevent theescape of such contents and cause the same to accumulate within theupsieve or screen, as shown at 9. The cylinder, worm, spider 8, andshaft 5 are all adapted to rotate in unison. A feed-hopper 10 projectswithin the upper end of the screen-cylinder and is apertured to permitthe passage of the A delivery-chute 11 extends from a point just belowthe lower end of the hopper in a downwardly-inclined 151ie tween theworm 7 and the feed-hopper 10 the 1 main body of the sifting-cylinderforms a Reference may be had to the accompany- 1 sifting-chamber, intowhich ashes are deposited, as desired, through the feed-hopper, the dustand finer particles of ashes escaping through the meshes of the cylinderand falling down through the open body of the inclosure into the barrelor can 3.

When it is desired to sift the ashes, the cylinder is rotated in adirection the reverse of that which w1ll impart a feed movement to theworm, in which case the worm acts as an obstruction or stop at the lowerend of the 1 through the feed-hopper until the desired quantity of asheshas been sifted and the de- 1 sired quantity of cinders has accumulatedper portion of the cylinder, which constitutes the sifting-chamber.

Referring to the drawings, wherein the invention is shown in preferredform, 1 represents an inclosure or box-like structure pro vided on itslower end with a cylindrical flange 2, adapted to receive the upper endof an ash can or barrel 3.

IVit-hin the mounted, in inclined position, a sifting-cylin der 4, fixedupon the shaft 5, having bearings in the walls of the inclosure, andprovided with an operating crank-handle 6. Fixed inclosure 1 isrotativelyy Within the sifting-chamber, after which the direction ofrotation of the cylinder is reversed, whereupon the worm 7 will causethe contents to he fed out from the lower open end of the cylinder intothe delivery-chute 11.

By the use of my improved sifter the sifting operation can be continuedas long as de sired, so that it is possible to secure cinders with aminimum of dust mixed therewith, and it is also possible to permit thecinders to accumulate within the cylinder until they are required foruse.

hat I claim as new, and desire to secure by Letters Patent, is

I. In an ashsifter, the combination with a sifting-cylinder rotativelymounted in inclined position and having in its upper end a upon theshaft 5 just within the lower end of siftingchamber; of a worm occupyingthe the sifting-cylinder is a worm 7 approxi- I lower open end of thecylinder; and means matelv of the same diameter as the interior forrotating the cylinder in opposite dlrecof the cylinder.

near its upper end by a spider 8, fixed upon the shaft 5, and at itslower end by the worm 7, the periphery of which may be connected Thecylinder is supported '1 tions.

at intervals with the wires of the cylindrical closure, and having inits upper end a siftingchamber; a worm occupying the lower open thecylinder in op osite directions.

3. In an ash-sitter, the combination with an inclosure; of asifting-cylinderrotatively mounted in inclined position within theinclosure, and having in its upper end a siftingchamber; a Wormoccupying the lower open end of said cylinder; means for rotating thecylinder in opposite directions; a feed-hopper extending interiorly ofthe incl osure and Withl l[ i l l 1 g in the open upper end of thecylinder; and a end of said cyhnder; and means for rotating idelivery-chute extending from a point below the lower open end of thecylinder, exteriorly of said inclosure.

In testimony whereof I have hereunto set my hand this 6th day ofOctober, 1906.

PATRICK M. STANTON.
